标题 :Precursors for synthesis of triphendioxazine dyestuffs
发明人：SCHWAIGER GUENTHER; SPRINGER HARTMUT; HELMLING WALTER
权利人:HOECHST AG
摘要:Water-soluble triphendioxazine compounds which have fiber-reactive properties as dyestuffs, which afford deep and fast dyeings on fiber materials, such as wool and, in particular, cellulose, and which correspond to the formula (1) ##STR1## in which: n is the number 0 or 1; n Y is the vinyl group or an ethyl group containing, in β-position, a substituent which can be eliminated by means of an alkali; n Q 1 and Q 2 both represent a benzotriazole radical which can also be additionally substituted in the benzene nucleus by alkyl having 1 to 4 carbon atoms, alkoxy having 1 to 4 carbon atoms, halogen, carboxy or sulfo; n B is --O--, --S--, --NH-- or --N(R')-- wherein R' is optionally substituted alkyl having 1 to 6 carbon atoms; n W 1 and W 2 both represent a divalent, optionally substituted aliphatic, cycloaliphatic, aliphatic-cycloaliphatic, araliphatic or aromatic-carbocyclic radical, it being possible for the aliphatic radicals to be interrupted by hetero groups --O--, --S--, --SO 2 --, --CO--, 1,4-piperidino, --NH-- and/or --N(R o )-- in which R o is optionally substituted alkyl having 1 to 6 carbon atoms or alkanoyl having 2 to 5 carbon atoms, and/or for aliphatic and aryl radicals to be attached to one another through such a hetero group; n R is hydrogen, alkyl having 1 to 6 carbon atoms, alkoxy having 1 to 6 carbon atoms, halogen, carboxyl or sulfo; n E is hydrogen, sulfo, carboxyl, a group --SO 2 --Y as defined above or an optionally substituted sulfonamide group; and n X 1 and X 2 are both hydrogen or halogen, cycloalkyl, alkoxy, aryloxy, aryl or another substituent; n and at least one carboxy, sulfo or sulfato group is present in the molecule (1), n and pre-products of those triphendioxazine compounds, of the general formula ##STR2## in which K is an amino or nitro group, Y' is β-hydroxyethyl or defined as for Y, W has one of the meanings of W 1 , and E' is hydrogen, sulfo, carboxy or a group of the formula --SO 2 --Y' defined above, or an optionally substituted sulfonamide group, and R, B and R* have the above meanings.

标 题:(Nitrofuryl)pyrazoles, their synthesis and use, and compositions containing them
发明人：RAINER GEORG
权利人:BYK GULDEN LOMBERG CHEM FAB
摘要:3-(5-Nitro-2-furyl)pyrazoles unsubstituted in the 5-position and 5-(5-nitro-2-furyl)pyrazoles unsubstituted in the 3-position are antimicrobials and disinfectants. The compounds are structurally represented by one of the formulae: ##STR1## wherein A is --CHO, --CN, --COOH, a protected or derived aldehyde group or a protected or derived carboxylic acid group; n B is 5-nitro-2-furyl; n R 1 is --H, substituted or unsubstituted hydrocarbyl (saturated or unsaturated; acyclic, alicyclic or aromatic; or araliphatic); substituted or unsubstituted (cycloaliphatic or aromatic) heterocyclic or acyl (carboxylic or carbonic acid); n R 2 is --H; and n n is a positive whole number of at most 2.
